your welcome.

if a 3 litre v6 jumps a couple of teeth om the cam belt whats the chances of valve damage?.its ronning as rough as hell and weve checked every sensor and the coil pack and plugs and leads and everythings working as it should.and te belt jumping is all that it can be and it sounds tappy from the top end

I think the consensus is that the belt has to skip 3 teeth before valves meet pistons (but don't quote me.....).

Both the Omegas I have owned have sounded a little tappety when cold so may be nothing to worry about (unless some valves are bent and have big clearances as a result).

First step has to be to take the bagpipes, auxiliary belt and cambelt cover off. Wind the engine round to TDC and check that the timing marks on the cam pulleys are aligned with the marks on the rear cambelt cover.

It is poss to bend the valves at 2 teeth belt jump and it also depends on what engine speed it jumped at, so yes you may have top end damage.

thought it was 3. also dependant on which way & what cam.

What's the belt history? When is it due?

Not too bad a job to check the timing marks.

Could post a video with audio....?

Have you done the paper clip test to look for any fault codes?

Go on Chris, I'm sure there are other members who would also appreciate it.

it has jumped 3 teeth and was drivin about 10-15mph wen it went iam just hopein there is no valve damage

There more than likely will be i'm sorry to say

Yes, if the top end has been rattling as a result the prognosis isn't good, I'm afraid.

Generally, you get away with 2, but not 3

returning to the OP, have you made sure that the cam sensor plug is actually connected to the cam sensor itself ?

"voltage too high" is signifying that the ecu is receiving maybe 12V when it's expecting 5V, which could be because it's plugged into the wrong place. Look at the wires and compare to the colours in the wiring diagram.

the omega is in a garage and all sensors have been checked and are fine. the timing belt has jumped 3 teeth the bloke at the garage is a family friend. he is gona time the old belt backup an check the compression and if valves are bent then i will have to break my baby due to the cost of putting it right which will be a great shame as the car is in extremely good condition and b4 this happend drove like a dream

If valves are bent, just replace the heads complete with second hand parts. There's always cars being broken here, & I'm sure it wouldn't be that expensive to put right.

either that or do what i did and just replace the engine got mine for £200 as i had lost compression on 3 cylenders
